This research applied the short-term diet control and training program to target the seven Judo professionals who often reduce weight in a short period of time and seven members of the social club who have no experience with excessive weight reduction in order to analyze change in the electrolyte, enzyme activation level in the body after a match and the excessive short-term weight reduction. The following conclusions were reached. 1. Change in the electrolyte 1) As for the change in the Ca, it was significantly low in the two groups during excessive reduction period, but it was significantly high after five minute-long match when it comes to excessive reduction(after six days). It was significantly low during recovery period. 2) As for the change in the Na, it was significantly high in the two groups when it comes to the appropriate reduction (after two days) compared to before the reduction. However, there was no change for the excessive reduction(after six days) prior to the reduction. Moreover, excessive reduction(after six days) was significantly high in the two groups after five minute-long match, and it was significantly low during recovery period. 3) As for the change in the K, it was significantly low in the two groups when it comes to the appropriate reduction(after two days before the reduction. Moreover, excessive reduction(after six days)was significantly low in the two groups after five minute-long match, but the recovery period was high. 4) As for the change in Mg, the two groups increased significantly during excessive reduction period. As for the excessive reduction(after six days), it increased significantly after five minute-long match as well, and it decreased significantly during recovery period. 2. Change in the enzyme activation level 1) As for the change in the LDH, it did not manifest significant change for the two groups during excessive reduction period, but it was high after five minute-long match after excessive reduction. It was low during recovery period. 2) As for the change in the CPK, it did not manifest significant change during the excessive reduction period in case of the group of Judo professional, but as for the group comprised of aficionados, it was significantly high in the appropriate reduction(after two days). In the two groups, they were high after five minute-long match for the excessive reduction (after six days), and they were low during recovery period. 3) As for the change in SOD, it was significantly low in the two groups during excessive reduction period, but it was significantly high after five minute-long match. During recovery period, it was significantly low in case of the group of Judo professionals, while it was numerically low in case of the group comprised of aficionados. The above mentioned results show that the Judo professionals in Korea can reduce weight excessively in a short period of time, with in 6-7% of the weight. However, when this weight reduction is continued for a long time, this can cause abnormal state. Thus, when the short-term weight reduction continues, it can exert negative impact on the electrolyte, enzyme activation level. Although there are differences in case of the Judo professionals depending on the individuals physical state and characteristics when it comes to the excessive short-term weight reduction, excessive weight reduction can produce negative results when it comes to the improvement of competition ability and on the condition before competition as well as competition ability. Result of this research will be leveraged, to produce important base data for conducting additional research to ensure improvement of competition ability when professionals exercise, following the scientific reduction method and appropriate short and long term periods for weight reduction.
